Mr. B. Is that any proof that you will not understand it when you do hear of it, Louisa? Do not allow yourself to be frightened by a hard name, my dear; it is a proof of great weakness of mind. Edward, endeavour to explain to your sister the meaning of the word anatomy.
Edward. I believe, papa, it is the study of animal bodies; more particularly, their internal organization.
Mr. B. Yes and it also implies the dissecting, or cutting them to pieces, to ascertain the structure and uses of their several parts. Well, Louisa, what do you now think of anatomy? You have been much pleased with your mother's description of the external structure and habits of the swallow, this morning; now pay the same attention to my account of the internal organization of the ostrich and cassowary, to- night, and I think you will find it quite within the limits of your comprehension.
Louisa. I will, indeed, attend, papa; and I hope I shall understand you.
Mr. B. The more minutely, my dear children, you investigate the hidden wonders of nature, the more firmly will you be convinced of the unlimited power, as well as infinite mercy, of its Supreme Author. The superintending providence of God, is as plainly manifested in the provision made for the meanest reptile, as it is in the wonderful formation of man. Each bird, beast, fish, and insect, is endowed with powers best suited to its wants, and most calculated to promote its enjoyment. In the cassowary of Java, a region of great fertility, the colon is no more than one foot long; whilst in the ostrich, doomed to seek its food in the wide and sandy deserts of the African continent, it is forty-five feet in length.
"Pray, papa, what is the colon?? enquired Louisa.
"It is one intestine," replied Mr. Bernard, which converts the food into nourishment. You will now instantly perceive the wisdom of this arrangement. In the cassowary, the food passes very quickly through this short channel, by which means, but a very small portion of its nutritive particles is taken into the system, and the bird is thereby preserved from many diseases, to which it would be liable, if the whole of the food it devoured were converted into fat and nourishment. The ostrich, on the contrary, who can gain but a slender supply of food in the desolate regions which it inhabits, is provided with a colon so long, that every particle of nourishment is extracted, before it has passed this channel; hence, the latter derives as much actual support from her slender supply of food, as the former does from her abundance.
Louisa. Thank you, papa. I understand what you have told us, quite well, and think it a very curious and a very wise contrivance.
Mr. B. Now then, tell me, in your turn, Louisa, how history has gone on since we last met.
Louisa. But, papa, we have not yet concluded the account of our walk. Had we not better finish one subject first?
